Laticrete Blue 92 Anti-Fracture Flexible Liquid Waterproof Membrane for Tile, Stone, Marble and Terrazzo Installations, Fast-Curing Crack Isolation Underlayment - 5 gal Pail (S-09200-NS-05)

Laticrete Blue 92 Anti Fracture Membrane is a premium professional grade crack isolation and waterproofing system engineered to protect tile and stone installations from substrate movement, moisture penetration, and long term surface damage. This advanced two part system combines a high performance liquid rubber compound with reinforcing fabric to create a highly flexible membrane that reduces crack transmission beneath ceramic tile, porcelain, thin brick, marble, natural stone, and cement based or resin terrazzo finishes. Once cured, it forms a durable protective layer that supports both residential and commercial installations in demanding interior and exterior environments.

The thin bed method of tile installation offers many advantages, but it can be affected by shrinkage cracking in concrete and movement in other substrates. These cracks can transfer through finished tile, stone, and grout joints over time, leading to costly repairs and reduced surface appearance. Blue 92 helps solve this problem by creating a flexible barrier between the cracked substrate and the finished surface before ceramic tile, marble, stone, thin brick, or terrazzo is installed. This makes it an excellent choice for new installations, renovation projects, and areas where long lasting crack prevention is essential.

This versatile tile membrane underlayment can be used when renovating older kitchen tile flooring, basement flooring, bathroom floor tile, shower areas, laundry rooms, patios, balconies, and other wet or high traffic spaces. It is suitable for vertical and horizontal surfaces, including ceilings, making it a reliable option for floors, walls, shower walls, bathroom surrounds, and interior or exterior workspaces. Its seamless spread creates a continuous, durable, and watertight waterproofing barrier that helps prevent leakage, water damage, moisture damage, mold growth, and deterioration beneath tile and stone surfaces.

Laticrete Blue 92 is designed to make installation easier for tile professionals, contractors, remodelers, and DIY users. The liquid membrane applies quickly with a paint brush or roller, requires no special equipment, contains no solvents or harsh fumes, and is non flammable for safer jobsite use. The reinforcing fabric strengthens the system while the liquid rubber technology enhances flexibility and dependable performance. Its fast curing formula dries in just a few hours to receive finished surfacing, helping save time and effort on projects of all scopes. Cleanup is simple with water while the material is still fresh.

With its Extra Heavy Service rating per TCNA performance levels and ASTM C627 Robinson Floor Test, Laticrete Blue 92 delivers durable load bearing performance for demanding tile and stone underlayment needs. The membrane adds no appreciable thickness to floor construction, allowing polymer fortified thin set mortar to be installed directly over the cured membrane. Each five gallon full unit covers approximately 300 sq ft. at 20 mil thickness, while the crack suppression kit covers approximately 75 linear ft. This makes Blue 92 a trusted waterproofing, hydro isolation, and crack prevention solution for bathrooms, kitchens, basements, commercial spaces, home decor upgrades, and professional tile installations requiring long lasting protection.
